Thank you for providing a detailed description of the issue you're encountering. It seems like the SelfQueryRetriever
is indeed converting your date string into a date object, which is causing the ValueError
.
To better assist you, could you please provide the following additional information:
metadata_field_info
? This would help in understanding how the metadata is being processed.SelfQueryRetriever
or the ConversationalRetrievalChain
?This additional information will help me understand the context better and provide a more accurate solution.
This response is meant to be useful and save you time. It is not meant to be a precise solution, but rather a starting point for your own research.

Here is the following metadata_field_info.
metadata_field_info = [
AttributeInfo(
name="source",
description="The document this chunk is from.",
type="string",
),
AttributeInfo(
name="origin",
description="The origin the document came from. Comes from either scraped websites like TheKinection.org, Kinecta.org or database files like Bancworks. Bancworks is the higher priority.",
type="string",
),
AttributeInfo(
name="date_day",
description="The day the document was uploaded.",
type="integer",
)
]
I am not sure which sample of data to provide. It looks like the SelfQueryRetriever is splitting up my question which includes a date in it. I am not sure this is in my data. I could be wrong.
The only configurations I have for the SelfQueryRetriever or ConversationalRetrievalChain is what I've already posted in the original snippet.

I have an updated response error now. I included more AttributeInfo metadata fields and it looks like it can split the question up better. However, there is a parsing error now.

Based on the error message you provided, it seems like the issue is with the filter query you're using. The error message indicates that the parser is encountering an unexpected token 'and' at line 1, column 34. This suggests that the parser is not able to understand the 'and' operator in your filter query.
The filter query you're using is: "eq(\"date_month_name\", \"January\") and eq(\"date_year_long\", 2023)"
. This filter query is trying to filter the documents where the date_month_name
is 'January' and the date_year_long
is 2023.
However, based on the error message, it seems like the parser is not able to understand the 'and' operator. This could be due to the fact that the parser is not configured to understand the 'and' operator, or it could be due to a syntax error in your filter query.
One way to resolve this issue is to check the documentation of the LangChain framework to see how to use the 'and' operator in filter queries. If the 'and' operator is not supported, you might need to use a different operator or method to achieve the same result.
Another way to resolve this issue is to check the syntax of your filter query. Make sure that the filter query is correctly formatted and that all the necessary parentheses and quotation marks are in place.
If you're still encountering the issue after checking the documentation and the syntax of your filter query, it might be helpful to look at similar issues in the LangChain repository. I found a similar issue in the LangChain repository: langchain.schema.OutputParserException: Could not parse LLM output: `. This issue suggests a workaround for the OutputParserException
error, which involves catching the exception and removing the prefix and suffix from the error message. This might not directly solve your issue, but it could give you some ideas on how to handle the error.
Here's the suggested solution from the issue:
@serving
def ask(input: str) -> str:
print("-- Serving request for input: %s" % input)
try:
response= agent_executor.run(input)
except Exception as e:
response = str(e)
if response.startswith("Could not parse LLM output: `"):
response = response.removeprefix("Could not parse LLM output: `").removesuffix("`")
return response
I hope this helps! If you have any other questions or need further clarification, feel free to ask.

Sorry, I'm still not sure what the best approach for this is? The query seems to be quite simple enough and based off of the examples demonstrated in the SelfQueryRetriever page this query should be handled just fine. @dosu-bot
🤖
Based on the error message you provided, it seems like the 'and' operator is not recognized by the parser. This could be due to the fact that the 'and' operator is not included in the allowed_operators
for the structured_query_translator
being used.
In the from_llm
class method of SelfQueryRetriever
, the allowed_operators
for the structured_query_translator
are set as follows:
if (
"allowed_operators" not in chain_kwargs
and structured_query_translator.allowed_operators is not None
):
chain_kwargs[
"allowed_operators"
] = structured_query_translator.allowed_operators
If the 'and' operator is not included in the allowed_operators
of the structured_query_translator
, it will not be allowed in the filter query.
To resolve this issue, you can include the 'and' operator in the allowed_operators
of the structured_query_translator
when you're creating an instance of SelfQueryRetriever
. Here's an example of how you can do this:
retriever = SelfQueryRetriever.from_llm(
llm,
vectorstore,
document_contents,
metadata_field_info,
structured_query_translator=structured_query_translator,
chain_kwargs={
"allowed_operators": ["and", "or", "<", ">", "=", "<=", ">=", "!="] # Include 'and' and any other operators you need
},
enable_limit=enable_limit,
use_original_query=use_original_query,
**kwargs,
)
Please replace llm
, vectorstore
, document_contents
, metadata_field_info
, structured_query_translator
, enable_limit
, use_original_query
, and kwargs
with your actual values.
You can find more details about this in the LangChain repository.
Regarding your question about whether the LangChain framework supports the 'and' operator in the SelfQueryRetriever
filter query by default, it does. This is evident from the RedisFilterExpression
class, which has a method __and__
that combines two RedisFilterExpression
instances using the 'and' operator. You can find more details about this in the LangChain repository.
I hope this helps! If you have any other questions, feel free to ask.

Even after setting the chain_kwargs allowed operators, I am still getting the same issue. Can I get some extra help on the matter?

chain_kwargs={
"allowed_operators": ["and", "or", "<", ">", "=", "<=", ">=", "!="] # Include 'and' and any other operators you need
},

Based on the information you've provided, it seems like the issue might be related to how the 'and' operator is being handled in the OpenSearchTranslator
class of the LangChain framework.
In the visit_operation
method, which is responsible for handling operations (including logical operations like 'and', 'or', 'not'), the _format_func
method should be called for the operator. This method is responsible for translating the operators and comparators from the internal domain-specific language to the OpenSearch query language. In the case of the 'and' operator, it should be translated to 'must'.
However, it appears that _format_func
is not being called for the operator. Instead, the operator is being directly used in the OpenSearch query, which is why the 'and' operator is not being recognized.
Here is the problematic code:
def visit_operation(self, operation: Operation) -> Dict:
args = [arg.accept(self) for arg in operation.arguments]
return {"bool": {self._format_func(operation.operator): args}}
To fix this issue, you should ensure that _format_func
is called for the operator in visit_operation
. The corrected code should look like this:
def visit_operation(self, operation: Operation) -> Dict:
args = [arg.accept(self) for arg in operation.arguments]
operator = self._format_func(operation.operator)
return {"bool": {operator: args}}
You can find this code in the libs/langchain/langchain/retrievers/self_query/opensearch.py file in the LangChain repository.
As for the allowed_operators
list, it is used in the LangChain framework to specify the operators that are permitted when constructing a query. This is particularly relevant in the context of the SelfQueryRetriever
and structured_query_translator
. If the allowed_operators
is not provided in the chain_kwargs
argument, it checks if the allowed_operators
attribute is available in the structured_query_translator
. If it is, it sets the allowed_operators
in chain_kwargs
to the allowed_operators
from the structured_query_translator
.
This allowed_operators
list is then passed to the load_query_constructor_runnable
function, which presumably uses it to construct a query. You can find this code in the libs/langchain/langchain/retrievers/self_query/base.py file in the LangChain repository.

@dosu-bot Can I get additional help on this from someone else? I don't want to go down a rabbit hole just in case.
It seems like this issue requires a deeper look, @baskaryan could you please lend your expertise?

Reproduction
I asked the following question:
The issue I got was
ValueError: Expected where operand value to be a str, int, float, or list of those type, got {'date': '2023-01-01', 'type': 'date'}
It looks like the SelfQueryRetriever converted my question that had January 2023 to a date object. This date object throws an error. I'm not sure how to resolve this issue on my end.
Expected behavior
Query with a date and receive an answer from the SelfQueryRetriever.
